Version
If no version is selected here, the latest SW with SIL capability is supplied. Alternatively,
the following SW version may be selected:
72: 01.00.zz, HART 7, DevRev01
Valid versions
• Firmware: from 01.00.zz (→ device nameplate)
• Hardware (electronics): from date of manufacture 28 February 2017 (→ device
nameplate)
3.2 Identification marking
SIL-certified devices are marked with the SIL logo on the nameplate.
3.3 Safety function
The device's safety functions are:
• Maximum point level monitoring (overfill protection)
• Minimum point level monitoring (dry running protection)
• Level range monitoring
The safety functions include level measurement of a liquid or bulk solid.
3.3.1 Safety-related output signal
The device's safety-related signal is the analog output signal: 4 to 20 mA. All safety
measures refer exclusively to this signal.
In the case of devices with one current output and one switch output (order code "020",
option "B"), only the current output (terminals 1 and 2) is approved for safety functions.
The switch output (terminals 3 and 4) can, if necessary, be wired for non-safety-oriented
purposes.
In the case of devices with two current outputs (order code "020", option "C"), only the first
current output (terminals 1 and 2) is approved for safety functions. The second output
(terminals 3 and 4) can, if necessary, be wired for non-safety-oriented purposes.
The device additionally communicates for information only via HART and contains all
HART features with additional device information.
The safety-related output signal is fed to a downstream logic unit, e.g. a programmable
logic controller or a limit signal transmitter, where it is monitored to determine whether:
• it exceeds and/or drops below a predefined point level.
• a fault has occurred, e.g. failure current (≤ 3.6 mA, ≥ 21.0 mA, signal cable open circuit
or short-circuit).
3) An additional selection of any additional versions is possible.
